Abstract

The damage process of crystal aluminum surface by powerful pulse beams of laser radiation has been investigated with the help of the molecular dynamics method. A direct transformation of beam energy into an energy of mechanical atomic motion is shown to be possible owing to a change of the Coulomb interaction screening in an ionic subsystem upon excitation of valence electrons.
